ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part ofLetterslEatent No. 705,788, dated July 29, 1902.

Application filed October 2, 1901. Serial No. 77,324. (No model.)

To all whmn it may concern:

Be it known that I, SAMUEL W. RAY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented new and useful Improvements in V Acetylene-Gas Generators, of which the following is a specification.

My invention relates to a carbid-feed .f or acetylene-gas generators; and the object of the same is to construct a device which will be operated by the fall of the gas-beIland a resilient diaphragm. by the simple and novel construction described in this specification and claimed, and illustrated in the accompanying drawings forming a part thereof, in which-r Figure 1 is an elevation of my generator and gasometer. Fig. 2 is a vertical longitudinal section of the same. carbid-receptacle. Fig. at is a detail horizontal sectionof'the carbid-receptacle.

Like numerals of reference designate like parts in the diiferent views of the drawings.

The numeral 1 designates the tank of my generator, which is normally filled with water up to the line 2. A stand-pipe 3, open at the top, is connected to the bottom of the generator 1 and is designed to serve as a water-gage and a safety-valve to relieve any excess of pressure caused by a stoppage in any of the pipes.

The generator 1 is connected at the top above water-line 2 to a pipe 4, which extends over and down into a purifier-tank 5, connected by a casing 6 to the generator and gasometer. The tank 5 is normally filled with water up to the line 7, and the open mouth of the pipe 4 is several inches below water-level. A pipe 8, having its open mouth above the water-line 7, passes down and out the side of the purifier 5 and into a gasometor -tank 9 through the gasometer, and connects with a gas-main 10. The tank 9 is filled with Water up to the line 11, and

vertical pipe 16 is connected to the outer end This is accomplished Fig. 3 is a detail of the of the pipe 8 and is immersed in an open cup 17, filled with water. This latter arrangement forms a water seal and a safety-valve which prevents an excess of pressure.

To provide asupply of carbid, a receptacle 18 is mounted on the apex of the generator 1. The receptacle 18 comprises two conical portions 19, connected by a portion snbstantially cylindrical, but having a flat side 20. 6c This flat side 20.faces the gasometer and con- 25, mounted in radially-extendingguides 25,

is connected to the short arm 24: by a rigid link 25 and is fitted in an aperture 26, which establishes communication between the receptacle 18 and the tank 1. The long arm of the lever 24 is connected by a chain 27 to the top of the gas-bell. By this arrangement the valve" 25 is operated positively in both directions. It is unseated by the descent of the gas-bell 12 and seated by the resilient action of the diaphragm 20 and the earbid fed into the generator as required.

In operation the tanks 1, 5,and 9 are filled with water up tothe levels indicated and the carbid-receptacle 18 filled by way of the opening in the top closed by a screw-plug 18. The carbid will trickle through alongside the valve 25 into the generator 1, and the gen- 9o eration of gas will start immediately. The gas will pass through the pipe l and be purified by the Water in the tank 5 and then flow into the gasometer by way of lhepipes S and 14:. The in [low of gas will raise the bell 1:3 and permit the diaphragm 20 to seat the valve 25 and cut off the supply of carbid. By dropping or letting out" links inthe chain 27 the, feed of the car-bid can be regulated to a nicety. It should be noted that the compo- I00 .nent of force at right angles to the lever causes compound flexure in the diaphragm,

which serves to return the lever to its normal position. i

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having described my invention, what I claim as new, and wish to secure by Letters Patent, is

1. In an acetylene-gas generator, the combination with a generator-tank and a gasometer provided with a bell, of a carbid-receptacle mounted on said generator and communicating therewith, a diaphragm mounted in the side of said receptacle, inner and outer couplings secured to said diaphragm, a short arm secured to said inner coupling, a longer arm secured to said outer coupling, a valve mounted in said carbid-receptacle, and connected to said short arm, and means for connecting said long arm and said bell, said means being constructed to exert a component of force at right angles to said lever-arm thereby causing compound flexure in said diaphragm, substantially as described.

2. The combination with a generator of a carbid-receptacle connected to the top of said generator, a diaphragm mounted in the side of said receptacle, a lever connected to said diaphragm, a valve mounted in said receptacle and connected to said lever, and means operated by the gas-pressure for actuating said lever, said means being constructed to exert a component of force at right angles to the said diaphragm thereby causing compound fiexure in said diaphragm, substantially as'described.

3. The combination with a generator and a gasometer provided with a bell, of a carbidreceptacle connected to said generator, a diaphragm mounted in the side of said receptacle, a lever connected to said diaphragm, a valve mounted in said receptacle and connected to the short arm of said lever, and a flexible member connecting said lever and said gas-bell, said member being arranged to exert a component of force at right angles to said lever thereby causing compound flexure in said diaphragm substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- Witnesses:

E. H. CONIBEAR, O. D. TRINKLES.
